Abstract(in English) This paper proposes four types of blind adaptive receivers for the multiuser demodulation in direct-sequence/code-division multiple-access communications. Although the spreading sequences and timings of all users must be known, the proposed receivers require no training signals. These consist of a bank of matched filters followed by a linear adaptive filter. Three of those are counterparts of the three types of blind receivers for the single-user demodulation: the minimum output energy receiver, the partitioned linear interference canceler and the maximum signal-to-interference-plus-noise ratio receiver. It is shown that these three receivers achieve the same performance in error probability as the minimum mean square error (MMSE) receiver. The fourth receiver is proposed to make use of the HJ rule which is known as a blind signal separation technique. Simulation results show that the performance of the fourth receiver is comparable to that of the MMSE receiver.
